"I'd like to see cell service shut down in a lot of places simply due to the lack of manners most people seem to have."

You may need one of these.....

"The CX 200 Portable Director II Cell Phone Jammer. Take a good look, because you may see a lot more of these little babies arriving here in the West once laws get changed, and people reach the end of tethers with loud mouths. The strange translation from Japanese says something like  secretly switch on  so its clearly covert. Uh-huh. Anyhoo, two modes, one gives 70 seconds jamming (i.e. peace) around you, the other fades out the call with natural atmosphere presumably to help you end calls youd rather not continue. Around $71.00.
